Abstract
A wireless power transmission device is provided. The wireless power transmission device includes a power input circuit, a communication module, a transmission coil, a power output circuit configured to apply output power to the transmission coil, and a processor. The processor may be configured to identify that a first input power is received from a first external power source through a first power input circuit, control the communication module to transmit first rating information corresponding to the first input power to the wireless power reception device, control the at least one communication module to receive, from the wireless power reception device, information on a first charging current determined based on the first rating information in the wireless power reception device, and control the power output circuit so that a first output power is applied to the transmission coil, based on the information on the first charging current.
